The image pixel dimensions and the print resolution (ppi) setting determine a print's size.
Print labs will use an appropriate print resolution, regardless what print resolution is assigned to files put on a disc.
Your main concern needs to be the pixel dimensions of the images on the disc.
Your camera makes photos that un-cropped are 4928 x 3264 pixels. At 240 ppi it will be a print that is 20.55 inches on the long side and 13.6 inches on the short side.
Here is the math - 4928 px / 240 ppi = 20.55 inches. 3264 px / 240 ppi = 13.6 inches.
If you assign a print resolution of 300 ppi the print size gets smaller. 4928 px / 300 ppi = 16.43 inches on the long side and 3264 px / 300 ppi = 10.88 inches.
The other consideration is the print shape, or aspect ratio.
Your D5100 makes photos that have an aspect ratio of 3:2 (4x6, 8x12, 16x24, etc), which is more rectangular than either 5x7 or 8x10.
In other words, to make a 5x7 or an 8x10 from the photos your D5100 makes, some of the image has to be cropped away from the long side of the photo.
